Origin and history

The chapel Saint-Sébastien, also known as Chapel Sainte-Claire, is a Catholic religious building located in Venanson, in the Alpes-Maritimes department. Built in 1481, it embodies a remarkable example of architecture and medieval painting in Nice. Its classification as historical monuments in 2000 underlines its heritage importance, both for its architectural characteristics and for its interior decor entirely covered with frescoes.

The chapel was erected at the entrance of the village of Venanson, probably in response to the plague epidemic of 1467, thus serving as a spiritual bulwark to protect the inhabitants. Its interior, decorated by the painter Giovanni Baleison, presents a complete cycle of frescoes dated 26 July 1481. These works illustrate in particular the life and martyrdom of St Sebastian, as well as scenes of daily life, patron saints and allegories of the virtues and capital sins. The cradle vault and flat bedside, typical of local religious architecture, house these wet paintings, made at the request of the village community.

Baleison's frescoes, of remarkable composition, offer a valuable testimony on the beliefs, clothing and tools of the late 15th century in the valleys of the Niçois hinterland. Among the scenes represented are Christ on the Cross surrounded by the Virgin Mary and St John, the martyrdom of St Sebastian pierced by arrows, as well as the figures of patron saint Saint Roch, invoked against the plague. The chapel, rectangular and covered with a two-slope roof, is distinguished by its stylistic unit and rich iconography, reflecting both local devotion and Italian artistic influence.

Classified as a historic monument since 26 May 2000, the chapel Saint-Sebastien is now owned by the municipality of Venanson. Its state of conservation and the quality of its murals make it a major site for the study of medieval art in the Alpes-Maritimes. The historical sources, including the works of Luc Thévenon and Philippe Beauchamp, underline his role in the regional religious and artistic heritage, while highlighting the work of Jean Baleison, a Niçois painter whose work remains an essential milestone in the history of Provençal art.

The chapel is part of a series of similar small buildings, built at the entrance of villages to ward off plagues like the plague. His iconography, combining hagiographic accounts and scenes of everyday life, makes him an exceptional visual document about the society of the time. The architectural details painted by Baleison, such as tool or clothing representations, complete this painting, providing historians and visitors with a tangible overview of the daily life and beliefs of the inhabitants of the Nice valleys at the end of the Middle Ages.
